Hillary cancels trip to Helsinki

From NBC's Andrea Mitchell, Courtney Kube, and Mark Murray
President Obama isn't the only one who has had to scrap overseas plans due to the volcanic ash emanating from Iceland.

Because of the continuing aviation problem in Europe, Secretary of State Hillary Clinton has canceled a trip tomorrow to Helsinki, where she was to give a speech. 

The State Department says she may still leave for a NATO meeting in Estonia -- but would not depart DC before Wednesday.

"Because of the continued aviation complications in Europe, the Secretary's stop in Helsinki has been cancelled; she will not be leaving tomorrow for Finland," a State Department official says. "We will let you know about the Tallinn portion of the trip when a decision has been made. IF we were to go to Tallinn, we would not leave Washington before Wednesday."
